Description

Technical Field

[0001] The invention relates to the technical field of magnetic imaging, and in particular to a magnetic imaging device based on a diamond film. Background Art

[0002] With the rapid development of science and technology and industrial production, the requirements for material performance are getting higher and higher. However, current metallurgical technology cannot provide perfect materials. Various equipment will also have defects in the production process, such as pores, slag inclusions, incomplete penetration in welding, shrinkage, pores, white spots, folds in forging, etc. These defects sometimes lead to equipment damage, causing major equipment and personal accidents, and causing significant economic losses.

[0003] Existing conventional nondestructive testing technologies include ultrasonic testing, X-ray testing, magnetic particle testing, eddy current testing, etc., but they all have some disadvantages, such as weak detection signals, signal coupling, complex situations, invisible electromagnetic signals, etc., and most detection devices are inconvenient to use and have low sensitivity.

[0004] For this purpose, the inventors in this field have proposed a magnetic imaging technology of diamond film, such as CN113176238B, a magnetic imaging device based on diamond film, in which the upper cavity of the shell of the present invention is connected with the lower cavity through a through slot; a laser emitting assembly and a camera assembly are arranged in the upper cavity, and the laser emitting assembly and the camera assembly are arranged at the two ends of the through slot respectively; a substrate is fixedly arranged at the bottom of the lower cavity, and a diamond film is fixedly installed in the through hole in the center of the substrate; the laser emitter of the laser emitting assembly and the CCD camera of the camera assembly are arranged tilted toward each other, and the extension lines of the laser emitter and the CCD camera intersect with the diamond film; four vertical inner grooves are arranged in the shell; two U-shaped silicon steel rods are arranged in parallel, and the two ends of the U-shaped silicon steel rods are inverted in the two adjacent inner grooves, and the outer surface of the U-shaped silicon steel rods is wound with a coil. Its beneficial effects are that the structural design is reasonable, and the magnetic field distribution pattern on the surface of the tested piece is finally obtained, and the sensitivity is high; it can overcome the problems of weak detection signal, signal coupling, complex situation, invisible electromagnetic signal, etc.

[0005] However, the device places the object in a fixed position for detection, and the bottom of the device is a diamond film, which not only easily causes damage to the diamond film, but also objects of different shapes and sizes, especially some special-shaped structures, cannot be fully detected.

[0006] To this end, inventors in this field have proposed a magnetic imaging device based on diamond film. By clamping and rotating the object, on the one hand, it is prevented from direct contact with the diamond film to avoid damage to it. On the other hand, by rotating the object, it can be examined from the front in all directions to avoid uneven detection caused by thicker parts. Summary of the invention

[0007] In order to solve the above problems, the present invention proposes a magnetic imaging device based on diamond film, so as to more accurately solve the problem that the above device fixes the object at its detection position for detection, and its bottom is the diamond film, which not only easily causes damage to the diamond film, but also the objects are of different shapes and sizes, especially some special-shaped structures, which cannot be fully detected.

[0008] The present invention is achieved through the following technical solutions:

[0029] In order to more clearly and completely illustrate the technical solution of the present invention, the present invention is further described below in conjunction with the accompanying drawings.

[0030] Please refer to Figure 1 - Figure 5 The present invention proposes a magnetic imaging device based on a diamond film, comprising a box body 1, a partition 11 is fixedly connected to the interior of the box body 1, and the partition 11 divides the interior of the box body 1 into two upper and lower spaces, a push-pull component is installed in the lower space of the box body 1, and an orientation component is installed in the upper space of the box body 1;

[0031] A transmission hole 12 is provided in the middle of the partition 11, and the transmission hole 12 is used to prevent the propagation of the detection light from being blocked;

[0032] The push-pull assembly includes a drawer 2, which is slidably connected in the lower space inside the box body 1. The top of the drawer 2 is rotatably connected with four rotating rods 3, and the end of the four rotating rods 3 away from the drawer 2 is rotatably connected with a placement plate 4, and a diamond film 5 is placed on the top of the placement plate 4. The placement plate 4 plays the role of placing the diamond film 5. A slide groove 6 is opened in the middle of the four rotating rods 3, and a slide groove 2 7 is opened on the inner walls on both sides of the lower space of the box body 1. A slide rod 8 is slidably connected between the two slide grooves 2 7, and a connecting plate 9 is fixedly connected to the middle of the slide rod 8. The middle of the connecting plate 9 and the end away from the slide rod 8 are fixedly connected with a push rod 10. The ends of the two push rods 10 are slidably connected to the inside of the four slide grooves 6 respectively;

[0033] When the drawer 2 is pulled outward, the rotating rod 3 moves with the movement of the drawer 2, and the rotating rod 3 simultaneously drives the push rod 10 to move and then drives the connecting plate 9 to move outward, and the connecting plate 9 drives the slide bar 8 to slide between the second slide groove 7. When the drawer 2 drives the slide bar 8 to move to the outer end of the two slide grooves 27, the slide bar 8 is restricted by the second slide groove 7 and cannot continue to move. At the same time, the connecting plate 9 and the push rod 10 are both restricted by them and cannot continue to move. At this time, the drawer 2 is continued to be pulled, and the slide groove 16 moves outside the push rod 10. When the push rod 10 contacts the bottom of the slide groove 16, the rotating rod 3 cannot continue to move, but under the pulling of the push rod 10, it will rotate upward along the rotating connection between it and the drawer 2, and then lift the placement plate 4, and at the same time lift the diamond film 5 through the placement plate 4, so that the diamond film 5 can be removed from the inside of the box body 1 for easy access.

[0034] The orientation component includes a motor 13, which is fixedly connected to the inner wall of the upper space of the box body 1, and the output end of the motor 13 is fixedly connected to a rotating frame 14, and the middle part of the rotating frame 14 is rotatably connected to a rotating frame 2 15, and one side of the rotating frame 2 15 is fixedly connected to a gear 16, and the right side of the motor 13 is fixedly connected to a motor 2 17, and the output end of the motor 2 17 is fixedly connected to a gear 2 18, and the gear 2 18 is meshed with the gear 16. When the motor 13 drives the rotating frame 14 to rotate, the rotating frame 2 15 is driven to rotate, and the motor 2 17 drives the rotating frame 2 15 to rotate through the meshing of the gear 2 18 and the gear 16, and the rotation directions of the two are vertically crossed, thereby realizing a 360-degree all-round rotation of the rotating frame 2 15;

[0035] The overall structure of the azimuth component is made of aluminum nitride, which has high hardness and strength and can be used as a support frame for the equipment. In addition, it has excellent optical transmittance and will not significantly affect the propagation of light. Therefore, its use in this equipment will not affect the detection work.

[0036] Two electric telescopic rods 19 are relatively installed in the middle of the rotating frame 15, and the output ends of the two electric telescopic rods 19 are installed with clamps 20. The electric telescopic rods 19 push the clamps 20 to move simultaneously toward the middle, thereby clamping the object. When the rotating frame 15 rotates, it drives the clamped object to rotate at the same time, thereby realizing all-round detection of the object.

[0037] In summary, when in use, an object is placed between the two electric telescopic rods 19, the electric telescopic rods 19 are started, and the electric telescopic rods 19 push the clamping claws 20 to move toward the middle at the same time, thereby clamping the object, and starting the detection device. During detection, the motor 13 is started to drive the rotating frame 14 to rotate, and the motor 2 17 is started at the same time. The motor 2 17 drives the rotating frame 2 15 to rotate through the meshing of the gear 2 18 and the gear 1 16. The rotation directions of the rotating frame 14 and the rotating frame 2 15 are vertically crossed, thereby driving the detection object to rotate 360 ​​degrees in all directions, thereby realizing all-round detection work;

[0038] In addition, since there may be foreign matter and dust on the detected object, they will fall onto the surface of the diamond film 5 as it rotates during detection. After the detection is completed, the drawer 2 is pulled outward, and the rotating rod 3 moves with the movement of the drawer 2. The rotating rod 3 also drives the push rod 10 to move and then drives the connecting plate 9 to move outward, and the connecting plate 9 drives the slide bar 8 to slide between the two slide grooves 7. When the drawer 2 drives the slide bar 8 to move to the outer end of the two slide grooves 7, the slide bar 8 is restricted by the slide grooves 7 and cannot continue to move. At the same time, the connecting plate 9 and the push rod 10 are also restricted and cannot continue to move. At this time, continue to pull the drawer 2, and the slide groove 6 moves outside the push rod 10. When the push rod 10 contacts the bottom of the slide groove 6, the rotating rod 3 can no longer move, but under the pulling of the push rod 10, it will rotate upward along the rotating connection between it and the drawer 2, and then lift the placement plate 4, and at the same time lift the diamond film 5 through the placement plate 4. At this point, the diamond film 5 can be removed from the interior of the box 1, which is convenient for taking the diamond film 5. After cleaning the diamond film 5, place it on the placement plate 4, push the drawer 2 in to put the placement plate 4 into the interior of the box 1.

[0039] Of course, the present invention may have many other implementations. Based on this implementation, other implementations obtained by ordinary technicians in this field without any creative work are all within the scope of protection of the present invention.
